Learn about a partner's problem before it becomes yours
FirmAPI continuously watches 38 public registers. When something changes at a monitored company – a new debt, insolvency, director change – a webhook delivers it into your system immediately.
Which changes we catch
Risk signals
The company appeared on a debtor list, entered bankruptcy, received an enforcement authorization or lost VAT reliability.
Business Register changes
Changes of directors, shareholders, registered address, business name, share capital or business activities.
Status changes
Entering liquidation, deletion from the register, legal form change.
Financial data
A new financial statement filed in the Register of Financial Statements.
How monitoring works
Subscribe companies
Via API or the dashboard, pick the IČOs you want to watch – customers, suppliers, competitors.
Set up a webhook
Provide your endpoint URL. Every delivered event is signed so you can verify its authenticity.
React automatically
The change arrives as a JSON payload with the event type, IČO and value diff. The rest is up to your system – from a Slack notification to freezing credit.

Frequently asked questions
How many companies can I monitor?
Depends on the plan – from a handful on the free plan to thousands on Enterprise. Monitored company and webhook counts are listed on the pricing page.
How quickly do I learn about a change?
The webhook fires immediately after the respective register's synchronisation catches the change. Most registers synchronise daily.
What if my endpoint is down?
We retry delivery with exponential backoff, and the delivery history is visible in the dashboard and via API.
Can I receive changes by e-mail too?
Yes, alongside webhooks we support e-mail notifications – handy when a person rather than a system watches the changes.
